McMorrows hammer method involves several applications of lacquer solution which renders the tension aspect of the hammer fairly inconsequential. In this case I agree with him that the staple is unnecessary. On tensioned hammers I do believe that the staple provides necessary support. That being said, the type of staple may make a difference. If the staple is not substantial enough to hold the tension then I would recommend a strong lacquer solution much like the reinforcers that you mention to stabilize the lower region of the hammer.

He says that Steinway calls this type of stapling "compression wiring" and that it is thought to help maintain the compression of the shoulders. On the other hand, Ed McMorrow seems to disagree, in his Educated Piano book, suggesting that the staples really serve no function (or are unnecessary) after the glue has dried, and are mainly to allow the hammermaker to buy some time by not having to leave the hammers in the press until the glue is completely dry.
